REVERSIBLE AND VENTILATING POT-HOLE RING FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 269,206, dated December19, 1882.

Application filed October 2, 1882. (Nb model.)

To all whom it may concern:

Be it known that I, WILLIAM HArLEs, a citizen of the United States, anda resident of the city of Albany, in the county of Albany and State ofNew York, have invented a new and Improved Reversible and VentilatingPot- Hole Ring for Stoves, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to a new and improved pot-hole ring which isreversible for operations in a stove, and in one position adapted to beused as a reducing-ring, the same as pot-hole rings heretofore made.While in a reversed position it will, in a stove burning hard coal, witha pot-hole cover over the same, operate to effect a dampening of thefire by its admitting air over the same, and with a cooking-vesselplaced on it the ring will operate to cause boiling or cooking toproceed slowly and without scorching the food; and when used in a stoveburning softcoal or wood the said ring,

with a cover placed over the same, will admit air into thecombustion-chamber to be mingled with the heated gases from the coal,and thereby contribute to their combustion before their escape to theexit-flue; and when employed with a hood inclosing a cooking-vesselsupported on said ring the ring will operate to admit the passage of thesteam and odors arising from the vessel into the combustion-chamher orflue leading from the same to the exit.

My invention in one part consists of a pothole ring formed by anexternal ring-flange and a verticallyprojecting flange provided with aseries of horizontal notches or ports made in its projected horizontalsurface, the ringbeing adapted to be supported from either of its sidesfrom the internal ring-flange made w.th the pot-hole of a stove-topplate. Inauother part it consists in the combination, with a stove-topprovided with a pot-hole, of this new pot-hole ring and a cover to thesame; and in anotherpart of myinvention itconsists in the combinationand arrangement, with a stove-top provided with a pot-hole, and a hoodadapted to be supported by the stove-top and envelopinga cooking-vessel,of the improved pot-hole ring hereinafter described.

The object of my invention is to provide a pot-hole ring which will beadapted to operate as a reducing-ring when in one position in astore-top, and in a reversed position, with a cover over it, operate toadmit the passage of air into the combustion-chamber to dampen down thefire when hard coal is used as fuel, and contribute to the combustion ofthe gases escaping from the burning wood or soft coal when used as a.fuel, and operate to admit the passage of the steam and odors escapingfrom a hooded cooking-vessel into the combusti0nchamber or a flueleading from the same. I attain these objects by means illustrated inthe accompanying drawings, in which- Figure 1 represents a sectionalelevation of a stove-top, my improved pot-hole ring, and acooking-vessel, the ringin position as a reducing-ring. Fig. 2 is asectional elevation of the same with the ring in reversed position andthe vessel enveloped by a hood. Fig. 3 is a perspective view of asection of my improved ring and a section of a stove-top, illustratingthe peculiar feature of the ring and its position when operatingdifferently from a reducing-ring. Fig. 4: is a plan view of the ringwhen serving the purpose of a reducing-rin g. Fig. 5 is a plan View ofthe ring when in position for admitting air or steam and odor to thefire; and Fig. 6 is a sectional elevation of the ring when covered by apot-hole cover and in position in the stove-top for the passage of airto the fire for dampening the same when hard coal is used as fuel, andfor burning thehot gases escaping from the top surface of the tire whensoft coal or wood is used as fuel.

The same letters of reference indicate like parts throughout the severalviews.

In the drawings, A represents the top plate of the stove, and a is thecombustion-chamber. B is a pot-holemade in top plate, A, and providedwith the usual flange'seat, b, all of which parts are well known.

0 is my improved and new pot-hole ring, which ring is made with form andouter diameter corresponding with that of pot-hole B it is to be usedwith. The said ring is composed of an outer or external flange, c,corresponding with the sunken flange-seat b of the pot-hole, and theinternal vertically-projecting flange, c. In the projecting horizontalsurface of flange 0 is made a series of notches, e, placed at intervalsapart, so as to produce a crenelled projecting flange. lVhen said flangeis covered over by a pot-hole cover or the bottom of a vessel the saidnotches operate as ports for the passage of air or steam and odors tothe tire below the stove-top.

In the drawings are shown an internal series of vertical notches, 6',extending from notches c downward through the entire vertical extensionof flange c, as shown. These notches c operate as vertical ports whenthe pit of a cooking-vessel sets within the opening of the ring, asshown in Fig. 2. \Vhen the ring is made to be used. with vessels havingplain flat bottoms these vertical slots may be dispensed with. Holespierced in and through flange 0 will serve the same purpose, though moreexpensive to produce than the notches.

When my improved pot-ring, is placed in position in the pot-hole, withits crenelled or port side downward,asshown in Figs.1 and 4:,theringwilloperate'asareducing-ring,thesame as an ordinary pot-holering, and Wlll operate as a seat for supporting a cooking-vessel ofsmaller diameter than that required to fill the pot-hole B proper of thestove. When the ring is placed in a reversed position in the pothole,with its crenelled side uppermost, as shown in Figs. 2, 3, 5, and 6, theoperations of the ring will be different and will be varied accordinglyas it is used, when hard or soft coal or wood is employed as fuel, witha cover or acooking-vessel only, or a vessel and hood inelosing thesame. When the ring is being used with a stove burning soft coal, and isplaced in the pot-hole in position shown in Figs. 2, 3, 5, and 6, andcovered by a cover, D, as in Fig.6, or with a vessel without a hood, thenotches or ports 0 will operate as passage-ways for the passage-of smallstreams or currents of air from over the stove-top into thecombustion-chamber to be mingled with the gases escaping from the topsurface of the fuelfand thereby contribute to their more perfectcombustion before escape to the exit.

When hard coal is employed as fuel and a cover is placed over the ring,as in Fig. 6, air will have passage from over the top ofthe stove intothe combustion-chamber, and a dampening of the fire will be efiected,and the rapid combustion of the fuel will be prevented, and allnecessity of tipping the covers for ventilating the apartment or coolingthe top plate of the stove will be obviated. With hard coal as fuel inthe stove, when a cooking-vessel is placed on the ring in position inFig. 2, without a hood, the passage of air from without into thecombustion-chamber will so afi'ect the combustion that cooking orboiling will procoed slowly and without scorching or burning thearticles of food being cooked. With hard or soft coal or wood as fuel inthe stove, when the pot-hole ring is placed in position in the potholeso that the crenelled or port side or flange is uppermost, and a vesselinclosed by hood H is supported on said ring, as illustrated in Fig. 2,the steam and odor escaping from the vessel will enter the chamberformed between the vessel and hood and pass thence through the severalports into the combustion-chamber, as they will be drawn by the draft ofthe chimney and made to mingle with the gases in their passage towardthe exit.

In Figs. 2, 5, and 6 arrows indicate the direction of the passage of theair and the steam and odor through the ports to the combustion-chamberunder the several conditions above mentioned, by which the severaloperations are effected by the use of my new and improved ring in stovesburning hard and soft coals, and with covers and with hoodedcooking-vessels, respectively, as above described, whereby an operatorwill have a more perfect control over the combustion of the fuel toincrease or lessen the same,and also better regillate the progress ofthe cooking being done.

By employing my crenelled or air-induction ring in a stove with a coverplaced over the same, and a vessel. placed on said cover and inclosed byhood H, (the cover arranged as illustrated in Fig. 6,) the process ofcooking may be made to be more slow than when the cover is not employed,and the vessel is supported directly from the top surface of the ring,as the cooking will be done substantially in a vacuum, with a plateintervening between the bottom of the vessel and the fire.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-- 1. A pot-hole ring having an external flange and anoffsetting internalflange provided with notches or ports, the formerextending horizontally from the latter, and the latter projectingvertically from one side of the former,
